Question

I am trying to run a deep learning python code written based on MASK-CNN deep network. And there is a C shared library "_crop_and_resize.so", I am trying to import it, but I am receiving the error "file too short. To note, ".so" file was created before by someone else, and I am trying to import it.Could you please let me know how to fix it?

g++ (GCC)= 9.3.0

python= 3.6.10

Ubuntu 20.04.4 LTS 64bit

    >>> import _crop_and_resize as _backend

    ***Traceback(most recent call last):

Per @AMIRABBAS's comment, the output of stat _crop_and_resize.so on the Ubuntu 20.04.4 LTS, 64 bit terminal is:

File: _crop_and_resize.so
Size: 0 Blocks: 40 IO Block: regular empty file

For whatever reason, when downloading the repository, it did not clone the file directly. Needless to say, you cannot link to a zero-length file.

For reference, having downloaded the same file directly from GitHub, the output should be:

~/downloads> stat _crop_and_resize.so
File: _crop_and_resize.so

I successfully downloaded the file, "_crop_and_resize.so" from its repository, and run it again and the current error gone and new error I am receiving!
